Champlain Hudson Power Express: Project Development Portal

Project Details

Meeting Clean Power Goals
  • The Champlain Hudson Power Express will supply up to 1,000 megawatts (MW) of clean, clean power to New York.
  • Bypassing transmission bottlenecks, this project will provide areas with growing energy demands access to new clean power that cannot be delivered through the current transmission system.
Preserving the Environment and Natural Views
  • The cables are only five inches in diameter and will be buried to avoid the visual impact of overhead transmission. Placing them underwater and underground is minimally invasive, will preserve natural views, and have a minimal impact on the environment.
  • The line will avoid the area of the Hudson being dredged for PCBs.
Safe, Secure Power
  • Because the HVdc cables are underwater and underground, these lines do not emit controversial Electromagnetic Fields (EMFs). Underwater transmission will make New York's aging energy grid more safe, secure, and reliable.
  • If the cable is damaged, HVdc protection reduces the current and voltage to zero in a fraction of a second so there is no possibility of damage to persons and infrastructure.
  • The HVdc transmission system uses underwater and underground cables that are solid, made from non-flammable materials, and well insulated and contain no liquids or gels. HVdc converter stations are solid state and contain no flammable fuel.
  • This project is not located in existing energy corridors and diversifies New York City's supply of energy. This diversity of supply feature will enhance the security of the state's power grid.
